4 Claims (Cl. 158-115) iFFIhis invention relates to a gas burner and ithas to do particularly with a gas burner for space heating purposes.

-This application is a division of copending application of..thisinventor, Serial No. 97,836, filed June 8, 1949, which has matured intoPatent Number 2,694,445, issued on November 16,1954. The gas burnerstructure of the present invention is admirably adapted as a conversionburner in the sense that it may be installed in a furnace which,previous thereto, was arranged to consume a dilferent type of fuel, suchas coal or oil, or the burner of the presentinvention may be used as areplacement for another'gas burner. On the other hand, the burner of thepresent invention, and particularly some of the features thereof, may beemployed with original equipment.

"The generabobjects of the invention are to provide a simplifiedlightweight burner and burner structure which can-be manufacturedeconomically so that the retailcost thereof may be reflected in theprice to the ultimate 'purchaser and user. A further feature is theprovision of-a structure which may be very easily serviced, this beingparticularly true in connection with the pilot.

A furnace structure made in accordance with the invention is shown inthe accompanying drawings:

Fig. 1 is a side elevational view of a burner constructed in accordancewith the invention showing the same mounted in a furnace with some ofthe furnace structure shown in broken lines.

Fig. 2: is a view largely in section taken on line 2 2 of Fig. 1 showinga mounting for the pilot support.

Fig.3 is'a sectional view taken on line 3-3 of Fig. 1 showing themounting for the pilot support.

Fig. .4 is a side elevational view of the supporting bracket for thepilot burner. I

Fig. 5 is an elevational view of the plates for closing the opening inthe furnace and showing how the plates are formed for receiving theburner, its support and the pilot support- I t Fig. 6, is an elevationalview of the outer end of the track for supporting the pilot burner.

The support for the burner advantageously comprises a member 1 and across piece 2 provided with floor engaging screw threaded studs 3 whichare threaded into the cross support and the inner end 5 of the member 1andwhich may be locked in position by nuts 4.

As shown in Fig. l, a portion of a furnace is illustrated at 8 and thesupport is disposed to lie partially within an area 9 within thefurnace. This is the lower part of the furnace and if the furnacepreviously used coal, the area 9 could have been the ash pit. The formergrate level of the furnace is indicated at about the broken line 10while the combustion chamber is illustrated at 11.

The compartment 9 is to be closed and this may be done by two sheetmetal members 13 and 14 secured together in their central portion byscrews 15 and fashioned to provide an opening 16. These members are alsofashioned so that when they are brought together they define an L shapedopening through which the body member 1 ICE.

of the support passes. One plate, such as the plate 13, is provided withan opening with a cover therefor, as shown at 17, which when inposition, leaves anopening 18 for purposes which 17 may be readilyremoved.

The mixing tube is shown tube 20 primary in Fig. 1 as having an outerprovided with secondary air openings 21 and air openings 22. The element20 is designed to telescopingly receive the main burner tube 45, whichis.

somewhat of L shape so that its free end extends upwardly as shown. Theburner tube supports a baflle or deflector 50 preferably in the form ofa pan shaped. stamping of heat resisting metal such as one of thestain-. less steels. the post is secured to the burner tube by means ofa member 52.

The described mixer tube and burner tube assembly is mounted on thesupport for which purpose the body member of the support is providedwith a number of U- shaped brackets each shown at 60, and a series ofclamps ened each by a screw (not shown). disposed within the furnacechamber and is of slightly larger size. as shown in Fig. l, with thetube with the parts so positioned that the secondary air apertures 21are disposed just outside the closure plates 13 and 14..

The pilot burner and the same may be easily withdrawn for service. atrack in the form of a 70, with its inner end mounted on the tube 45as:by

means of a clamp 71 and the extreme innerend is folded back upon itselfto provide a hook 72. Clamp 71 may comprise a split collar secured bysuitable means to bar? 70 and encircling tube 45, the ends of the collarbeing. drawn together for clamping the tube by a screw as illus trated.The intermediate portion of this bar is inclined of the track whichextends out through'the plates 13 and 14 is preferablythorizontally 1 asat 73 and the portion disposed and is supported by a bracket 74 carriedby the support member 1 near its outermost end is (Fig. 6).

78 in the form of a strip mating in a substantially support has a struckout track 70 and a notch 82 with an upturned part 79 termiverticallydisposed end 80. The hook 81 for slidably fitting over is provided forengagement within the hook 72. The support 78 has a struck out andturned down portion which forms a hook 83, the notch left by the struckout hook being illustrated at 83a (Fig.4). H U In the normal'position ofthe parts, the hook 72 em braces the support in the notch 82 which thebook .81] rests upon the track and the hook 83 is fitted in the notch.76. The pilot burner is secured to the upstanding end of,

pilot burner being shown at 85and from, f the burner a'pilot flame as at86 burns. 'Thegas conthe support, the

will presently appear. The cover A post or rod 55 supports the deflectorand,

its support are so arranged that: There is bar or strip of metal, as at(Fig. 2). This bracket has struck" out lugs which receives and supportsthe track. The track'- provided with a notch 76 The pilot burner supporthas a horizontal body portion 3 conductors as indicated at 91, extendingalong and secured'to the support aridextending through conduit 89.

As heretofore explained, the closure panels '13 and 14 and,specifically, the removable closure 17 is provided with an opening 18forsnugly receiving the composite cross-structure ofthe' track and pilotsupport so that the sameextends therethrough, as shown in Figs. 1 and 5.Should the pilotburner need service, such, for example, for cleaning orshould the temperature control device need service, the plate 17 isremoved and then the outer end of the support 78 is slightly elevated sothat the hook 815 is removed from the notch 76 and then the support ispulled outwardly. In this action the book 81 rides along the track andthe inner end of the support may be pulled through the opening to theoutside of the closure plates 13 and 14 for the'service operation. Toreplace the pilot the support is merely pushed inwardly, the hook 81rides up the incline on the track and the support comes to rest as itengages in' the hook 72 whereupon the hook 83 is engaged in the notch76. To do this, of course, it will be necessary to uncouple the outsideconnections for the conduit 87 and the leads 91for the temperaturesensitive device.
